LA CROSSE, Wis. (WKBT) -

A recent Polio outbreak has caused concern in the Middle East.

There has been 68 cases of the virus confirmed this year, that number is up from 24 this time last year.

The World Health Organization has called for states within the outbreak to declare a national public health emergency. Contaminated water as well as person to person contact are the main causes for the spreading. While people in the United States have no need for concern just yet, it's important to know how to prevent coming in contact from the virus.

"Be aware of the areas and of course as we always say when you're traveling overseas not to drink the water, to drink only bottled water, and even to be swimming in water that is unclean you should really be careful of it," said La Crosse County Public Health Nurse Joann Foellmi.

In order to make sure you are protected, County Health officials also said to be up to date on vaccinations before traveling.
